Abstract

Process control technologies are widely used in industrial control systems, and engineers who understand process control are largely in demand. Thus, there is a strong need to offer process control course to electrical engineering technology students. In this paper, we present our experience in providing laboratory experiments for a process control course in electrical engineering technology. In general, this course provides an overview of process control principles and practices. Topics include analog and digital signal conditioning, temperature sensors, mechanical sensors, optical sensors, final control, discrete-state process control, and proportional-integral-derivative (PID) controllers. We devote more time to the study of the PID controller in particular because there are so many applications in various industries. For example, power plants need a PID controller to obtain desired control performances. However, teaching mere theoretical concepts to students is often challenging because such concepts require teaching advanced mathematics that are difficult to comprehend. As an alternative pedagogical method, we provide these concepts to students through laboratory experiments, as it is very important for electrical engineering technology students to acquire hands-on training. To facilitate understanding of the PID controller, we use the Amatrol T5552 process control learning system that has a built-in Honeywell PID controller. In order to see the effects of different control types, we experiment in three different control modes: (1) Proportional (P) mode, (2) Proportional-Integral (PI) mode, and (3) Proportional-Derivative (PD) mode. We analyze each control mode characteristics and draw comparisons among all control modes. Finally, we provide student course assessment and course evaluation feedback to illustrate the effectiveness and satisfaction of this laboratory experiment-focused approach.
